Quick Detail:

Bartec Type --- Upset forging parallel thread connect rebar couplers 

Bridging rebar splicing— Embedded rebar splicing   

First type: LER — suit to connect two fixed reinforcing bars, or two fixed concrete   

Advantages of LER Adjustable Coupler

There has two thread rebars which have been processed in the construction site, they are all embedded or have fixed reinforcement cages, such as the above LER connection. The one side is embedded concrete reinforcing bar, another side is reinforcing bars which are fixed in reinforcement structure, this connection doesn’t need to rotate two steel bars and can connect two fixed reinforcing bars together simply.

The advantage is that don’t need to do adding length thread, or left and right thread in the reinforcing bar. All thread of reinforcing bars are processed normally, pouring in concrete normally, it is very convenient in site construction, and the design of drawing is also more sample and relaxed.
